Specification of Letters Patent.

Patented May 21, 1907.

Application filed April 9', 1906. Serial No. 310,686.

To all whom it may concern:

Be it known that 1, JOHN D. R. LAMSON, a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Pencils, of which the following isa specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in pencils for holding detachable lead crayons and more especially to that class of pencils shown and described in my Letters Patent of the U. S. dated November 22, 1904, and numbered 775,493.

The object of this invention is to provide a simple and cheap construction which is strong and rigid and to provide simple and efficient means for moving the crayon along its tube and holding the same from being forced inward by the pressure thereon, in writing.

It is also an object of the invention to provide the same with certain other new and useful features and the several advantages of the particular construction, arrangement and combination of parts, all as hereinafter more fully described reference being had to the accompanying drawings, in which Figure 1, is a longitudinal section through the axis of a device embodying the invention and showing the same on an enlarged scale; Fig. 2, a transverse section of the same on the line acw of Fig. 1; Fig. 3, a similar section on the line y@ of Fig. 1; Fig. 4, is a longitudinal section through a portion of the body taken on a plane at right angles to that of the section of Fig. 1; Fig. 5, is a perspective view of the body of the pencil with parts broken away to show the construction; Fig. 6, is a perspective view of thepoint of the pencil; Fig. 7, .a perspective view of the spring follower; Fig. 8, a similar view of the eraser cap or tip; Fig. 9, is a perspective view of the pencil partly in section and showing a modified construction; and Fig. 10, a similar view showing another modification.

In the drawings, 1 is the body or barrel of j the pencil formed from a blank of sheet metal which is rolled into cylindrical form with a longitudinal slot 2 along one edge 3 of the blank and the metal at the other side of the slot is carried radially inward and turned along its edge into a small tube 4, said inwardly extending part, forming a connecting web 5 to support the tube 4 in the axis of the barrel. The blank is so formed that the tube 4 will have an end 23 projecting some distance beyond the forward end of the barrel, or to the extreme point of the pencil. Between the inner edge 6 of the blank and the web 5 is a small space forming a longitudinal slot 7 in said tube opposite the slot 2 in the barrel and this edge 6 is provided with notches 8 along the slot to be engaged by the laterally bent tail piece or end 9 of a follower 10 consisting of a strip of spring steel adapted to slide along in the slots 2 and 7 beside the web 5 with its upper notched or otherwise roughened edge 11 projecting from said slot 2 to be engaged by the thumb of the operator to move the same forward or toward the point of the pencil. The lead crayon in the crayon tube 4 may thus be moved to proj ect the same from the point of the pencil and is held against inward pressure when so moved, by the engagement of the tail of the follower with said notches. The follower being formed of thin spring steel may be lifted out of the slot at any point when it is desirable to insert a longer crayon and again inserted behind the crayon, the engagement of its tail piece with the tube frictionally holding it in place against accidental displacement.

Instead of forming the follower with the tail piece and providing notches on the crayon tube, notches 12 as shown in Fig. 9, may be formed in the edge 3 of the barrel and the follower 13 curved so as to engage said notches, or, as shown in Fig. 10 the web 5 may be provided with a series of holes 14 or suitable indentations adapted to be engaged by a projecting member 15 on the follower 16.

The tapering end of the pencil or point portion 17 is also formed of sheet metal rolled or stampedinto a conical form with a base flange 18 of a diameter to fit closely within the end of the barrel 1. An inwardly pressed groove 19 is formed at the junction of the conical and flange ortions, and a short slot 20 extends inward rom the end of said flange to the groove at the side of the flange, opposite the seam or abutting edges 21 of the sheet metal forming the point portion. On the edge 3 of the barrel is provided at its forward end a short inwardly turned lip 22 and when the flange of the point portion is inserted in the end of the barrel, the web 5 and lip 22 are received within the slot 20 thus preventing the barrel from spreading at its forward end. After the insertion of the flange, the edge of the metal at the end of the barrel is turned or pressed down into the groove 19, and. thus the point and barrel are interlocked to pre vent spreading and the point firmly secured in place without soldering or brazing with the end 23 of the crayon tube in the opening at the end of the point. This projecting end '23 of the tube may be slightly contracted to frictionally engage the crayon and prevent its dropping from the tube.

.The rear end of the barrel is held from spreading by a sheet metal thimble 24 also forming a cap or tip for holding an eraser 25, and the slot 2 in the barrel is held open by a lip 26 struck down from the body of the thimble to engage said slot.

Having thus "fully described my invention,

. what I claim is whereby the body with its crayon tube and follower engaging means may be formed from a suitably shaped sheet metal blank, and a follower to slide within said slots with one edge projecting therefrom and having a bent portion engaging said means.

2. In a pencil, the combination with a cylindrical body having a longitudinal slot and a crayon tube in the axis of said body having a longitudinal slot opposite the slot in the body, of a follower to slide within said slots with one edge projecting from the slot in the body and formed of a flat piece of spring steel bent laterally to engage the edge of one of the slots, whereby said follower may be lifted from said slotat any point of its travel along said slot.

3. In a pencil, the combination of a cylindrical body formed of sheet metal with a longitudinal slot along the longitudinal edge of the metal and a portion of the metal turned inward along one edge of said slot and the inner edge of said portion rolled to form a crayon tube in the axis of the body with a longitudinal slot opposite the slot in the body and notches in the edge of the metal along the edge of the slot in the tube, and a follower formed of a strip of sheet metal within said slots and having a laterally bent end to engage said notches.

4. In a pencil, the combination with a cylindrical body formed of sheet metal and provided with a longitudinal slot along the longitudinal edge of the metal, adjacent'inssaese wardly turned portions at one endv of said slot, and a conical end. formed of sheet metal adapted to fit within the end of the body and provided with a slot to receive the inwardly turned portion.

5. In a pencil, the combination of a cylindrical body formed of sheet metal and provided with a longitudinal slot along the longitudinal edge of the metal, a portion turned inward along one edge of said. slot to l'orin a connecting web, the inner edge of said web portion turned to form a crayon tube in the axis of the body with a longitudinal slot opposite the slot in the body, an inwardly turned lip on the body at one end. oi said slot therein, and a conical-end formed of sheet metal and provided with a .llange to lit within the end of the body having a slot to receive the web and lip. V

6. In a pencil, the combination of" a cylindrical body formed of sheet metal w ith. a longitu .linal slot along the longitudinal edge oi" the metal, a portion turned inward along one edge of said slot to term a radial web in the body, a crayon tube in the axis ol the body formed by rolling the edge of the web, said tube extending longitudinallybeyond the end of the body to the point ol the pencil, an inwardly turned lip at one end of the slot, a conical end formed of sheet metal adapted to receive the extended end of the tube, and a. flange on the conical end to lit within the end of the body and :lormed with a slot to receive the web and lip and with a groove into which the edge of the metal at the end of the body is pressed to secure the conical end. to the body.

7. Ina pencil, the combination of a cylindrical body formed of sheet; metal with a longitudinal slot extending along the longitudinal edge of the metal, inwardly turned portions extending imvard 'from each edge of the slot at one end thereof, a conical end formed of sheet metal and having a ilange to it within the body provided with a slot to receive the inwardly turned portions, a crayon tube in the axis of? the body, a 'lollower adapted to slide within said slot with its upper edge projecting therefrom, an eraser cap to -lit over the end. of the body opposite that to which the conical end is secured, and a lip on said cap to enter the end ol the slot in the body and hold the same open to permit the free movement of the follower.

In testimony whereof I allix my signature in presence of two witnesses.

JOHN D. it. LAMSON.
